Davon Allen
Gameplay Programmer
Unreal C++ I Unity C#
I build gameplay systems across Unreal Engine and Unity, with a focus on gameplay systems, multiplayer-safe architecture, and designer-facing tools.
My work spans live UEFN multiplayer islands, Unreal C++ prototypes, Unity production tooling, AR/VR installations, and educational game systems.
This portfolio highlights systems I owned from prototype through production, with notes on architecture, tradeoffs, debugging, and impact.
